OILER.

SPECIFICATION forming part of Letters Patent No. 579,627, dated March 30, 1897. Application filed June 29,1896. Serial No. 597,372. (No model.)

To all whom it may concern.

Be it known that I, WILLIAM C. WILsoN, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Oilers, &c.; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in Which Figure 1 is a vertical sectional view of an' apparatus made according to my invention in a closed condition. Fig. 2 is a like view of the same in an expanded condition for use. Fig. 3 is a perspective view showing a modified form of the apparatus. Figs. 4 and 6 are sideviews and partial sectional views showing certain modifications of my invention, and Fig. 5 is a plan View of the same.

This invention relates to vessels provided with means for supplying and distributing liquid lubricants in variable quantities and commonly designated as oilers, but which may -be used for other and analogous purposes when desired.

Said invention comprises certain novel combinations of parts whereby provision is made for the supply from any suitable vessel or reservoir of a fluid lubricant or other liquid in easily and accurately controlled quantities, and whereby on occasion the vessel itself may be hermetically closed for carriage, laying aside, or other purpose when not required for immediate use.

Ais the body or oil-reservoir,which contains the liquid to be distributed. The shape and size of this reservoir may be varied according to the special purpose for which the oiler or the like is to be used. Thus in the drawings, Figs. 1 and 2 are designed to represent large oil-cans, such, for example, as those very commonly employed for vending illuminating-oils by the gallon and multiples thereof, although a like structure of lesser size may be employed as an oiler for supplying oil to the bearings of machinery, to journal-boxes, or the like.

Fig. 3 shows a cylindrical reservoir more especially adapted to general uses of an oiler where only a moderate supply of lubricating v material is required, and Figs. 4 to 6, in-

clusive, show a comparatively small, flat, and substantially rectangular reservoir adapted to be carried in the pocket and especially intended for oilers to be used with bicycles, &c.

The internal structure of the apparatus, with the exceptions hereinafter specifically set forth, is substantially the same in all the apparatus represented in whole or in part in the drawings. This structure, with the eX- ceptions justindicated,is represented in Figs. 1 and 2.

Within the reservoir, and extended from the bottom to the top thereof, is a cylindrical sleeve B. This sleeve is open externally at its upper end by a wide throat, as shown at a, and at bottom by an opening I). The interior of this sleeve communicates with the interior of the reservoir by an orifice c at or near its upper end. The upper end of this sleeve terminates in an externally-threaded annulus or annular nut A of corresponding internal diameter. Within this sleeve is a conical or tapering tube 0, the smaller upper end of which is open, as at d, and the larger lower end of which is over the opening I) in the bottom of the reservoir, so that when a passage is afforded through said tube air may pass from outside the reservoir into the latter when the liquid contents of the latter are withdrawn. Thrust into the tube O through the opening I) is a stem D, which for convenienoe of use and operation may have a knob e at its outer end. When this stem is pushed inward to its limit, it closes the passage through the conical tube. When withdrawn to any extent, it proportionately opens said passage.

E is a longitudinally-movable tapering nozzle which is open attop and bottom and which is provided with an opening, for example, as at f, at or near its lower end, which on occasion is brought coincident with the opening 0 of the sleeve and which is so formed and arranged that when moved inwardit surrounds the tapering tube 0 with its lower part snug against the circumference of the adjacent part of the tube and is itself inclosed within the sleeve B and practically below the throat a. With the nozzle in this position a screw-cap F is screwed upon the threaded annulus A, and thus closes the top of the reservoir, as

shown in Fig. 2. The stem D being thrust inward to its limit to close the passage through the tube E, the reservoir is hermetically sealed and in this closed and compact form and condition may be readily carried from place to place without danger of spillingits contents, and, as the nozzle is inclosed within it, without danger of breakage of or injury to any projecting part.

To fit the apparatus for use and operation, the cap F is removed and the nozzle is drawn outward through the throat a untilits tapered lower end fits snugly into the tapered or conical scat provided by the tapering interior of the annulus, as shown in Fig. 1. By this means the nozzle is frictionally held in position with sufiicient firmness for all practical purposes. In bringing the nozzle to the position last described the openingf thereof is brought coincident with the opening 0 of the sleeve, so that communication is established from the interior of the reservoir to the interior of the nozzle at its base or inner end. hen the nozzle is thus extended, its tapering lower part being in juxtaposition with the relatively cylindrical internal orifices of the annulus A provides an annular chamber a which receives all drip from the outside of the nozzle, the drip passing down into the reservoir when the nozzle is thrust inward, as explained.

In use and operation with the nozzle extended, as described, the apparatus is tilted, inverted, or inclined, as the case may be, and flow of liquid therefrom is controlled by adjustment of the stem 1). sage afforded through the tube 0 is slight, the outflow of lubricant is proportionally slow and may be in drops, and when the capacity of such passage is increased in a like ratio the outflow may lie in a continuous stream of greater or less dimensions.

In Fig. 3 the nozzle is shown with alateral beak I), so that the outflow may be directly vertical downward from the nozzle. In this figure also instead of applying a cap F to a threaded annulus A, as in Figs. 1 and E2, the cap is screwed upon a screw-thread 0 formed in the circumference of the reservoir at the upper part thereof.

In the structure shown in Figs. 4 to 6, inclusive, the fixed nut or annulus is indicated by reference-letter g and is sunken so that its upper side is flush with the top of the reservoir. The cap is substantially a nut, in this case indicated by the reference-letter h, fast upon the nozzle and movable therewith. The latter being capable of an axial movement is, when depressed, turned around to screw the movable nut h of the nozzle into the fixed nut of the reservoir, thus closing the latter. By unscrewing the nut h from the nut the former is liberated and the nozzle may then be drawn out to its limit, whereupon this apparatus maybe used as described with reference to Fig. 1. The nozzle may have at its outer end an elongated horizontal hen the pasbeak f so arranged that in the use of the apparatus the beak projects beyond the sides of the reservoir, thereby facilitating the use of the apparatus for various purposes. This beak should be so arranged that when the reservoir is closed by the nut h, the beak will lie along the top of the reservoir out of the way, as shown in Fig. 5. In this construction the nozzle and the tube 0 instead of being tapering throughout may be of cylindrical shape at their upper parts, as shown in Figs. t. and 6, and of tapering form at their lower parts. hen desired, a slip-cover m maybe placed over the reservoir when in its closed condition to conceal the beak and provide a neat external appearance to the apparatus.
